A spinner is separated into 5 equal pieces, as shown below: patrick spins the spinner 9 times. what is the theoretical probability that it stops on the brown sector on the last spin?

Answers

Answer 1

To solve this problem, let us first define what probability means in this case. It would be:

Probability = (number of colors to choose from) / (total number of colors)

There are a total of 5 colors on the spinner. The number of colors to choose from spins 1 to 8 would be 5 out of 5, while for the last spin 9 the number of colors to choose from would only be brown so that would be 1 out of 5. The total probability would be the product of the probability of each spins, therefore:

Probability = 1st spin * 2nd spin * 3rd spin * 4th spin * 5th spin * 6th spin * 7th spin * 8th spin * 9th spin

Probability = (5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5) * (1/5)

Probability = 0.2

There is a 20% chance to get brown on the last spin.

Answer 2

Answer:

1/5

Step-by-step explanation:

Think of it like this. If there is five spots it can potentially land on, and only 1 brown spot, the answer would be 20 %, or as a fraction, 1/5.

Two points in the xy plane have cartesian coordinates (2.00, 24.00) m and (23.00, 3.00) m. determine (a) the distance between these points and (b) their polar coordinates

Answers

Final answer:

The distance between the two points is approximately 29.70 m. The polar coordinates of the points are approximately (24.20 m, 1.46 radians).

Explanation:

To find the distance between two points in the Cartesian coordinate plane, we can use the distance formula.

The distance between the points (2.00, 24.00) m and (23.00, 3.00) m is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values, we get:

d = sqrt((23.00 - 2.00)^2 + (3.00 - 24.00)^2)

d = sqrt(441 + 441)

d = sqrt(882)

d ≈ 29.70 m

The polar coordinates of a point (x, y) can be found using the formulas:

r = sqrt(x^2 + y^2)

p = atan2(y, x)

Plugging in the values, we get:

r = sqrt(2.00^2 + 24.00^2)

p = atan2(24.00, 2.00)

r ≈ 24.20 m

p ≈ 1.46 radians

Answers

Calculate first the area of the shaded triangle region and the area of the square then you could get the probability of the point
The formula for the area of triangle is b h / 2
Where:b = h = half of side length of square = 9 mm
Area of triangle = 9 mm * 9 mm / 2
Area of triangle = 40.5 mm^2

Area of square = s^2
Area of square = (18 mm)^2
Area of square = 324 mm^2

Probability that a point is in the shaded region
= Area of triangle / Area of square
= 40.5 / 324
= 0.125

B. g(x) = 5x – 10
C.g(x) = 5x – 9
D. g(x) = 5x – 10

Answers

The easiest way to test it is to sub in (2,15) and see which is holds.

Your function f(x) should be 5^x, instead of 5x

Answer should be g(x) = 5^x - 10, since it shifts f(x) downward by 10 units

The equation of the function is , g(x) = 5x -10 , Option B is the right answer.

What is a Function ?

A function is a mathematical representation of an independent variable and a dependent variable.

The given function is

f(x) = 5x

As the y intercept is shifting from (0 ,1) to (0,-9)

therefore the function is translating 10 points down

therefore the equation of the function is

g(x) = 5x -10

Therefore Option B is the right answer.

How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?

Answers

The graph has been moved 3 units downward, making the range change. The range of f(x) is [-5,5], while the range of g(x) is [-8,2]. The picture is of both functions. f(x) is blue, g(x) is red.

Answer:

[-8,2]

Step-by-step explanation:

We are given that the function f(x) is transformed to the function g(x), where,

[tex]f(x) =-5 \cos 2x[/tex] and [tex]g(x) =-5 \cos 2x-3[/tex].

Since, the range of [tex]\cos x[/tex] is [-1,1].

Thus, the range of [tex]a\cos bx[/tex] is {-a,a].

So, the range of [tex]f(x) =-5 \cos 2x[/tex] is [-5,5].

As, we are translating the function f(x) 3 units downward to get g(x).

The graph of the function is shifted 3 units down.

So, the range of g(x) will be [-5-3,5-3] = [-8,2].

Hence, the range of [tex]g(x) =-5 \cos 2x-3[/tex] is [-8,2].

Which represents the equation of the side that is parallel to side s?

Answers

With two points you can define a line.

So, the line parallel to s is q, which has these two points: (3,6) and (6,3)

There are different ways to get the line. For instance, this one:

y = a*x+b,

a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,

y = -x + b,

Now use any point, say (3,6) to get b:

6 = -3+b-> b = 9,

line is y = -x + 9,

It checks out in the other point: (6,3) --> 3 = -6+9 = 3. Good.

Other method could be:

y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.

Hope it helps!

The side that is parallel to side s is side q. The equation of side q is: y = -x + 9.

What is the Equation of a Line?

We can represent the equation of a line as, y = mx + b, where m is the slope of the line and b is the y-intercept.

The side that is parallel to side s is q.

Slope (m) of q = change in y / change in x = (6 - 3) / (3 - 6) = 3/-3 = -1.

Substitute m = -1 and (3, 6) = (a, b) into y - b = m(x - a):

y - 6 = -1(x - 3)

y - 6 = -x + 3

y = -x + 3 + 6

y = -x + 9

Two men, 400 feet apart, observe a balloon between them; it is in the same vertical plane as they are. The respective angles of elevation of the balloon are observed by the men to be 75°20' and 49°30'. Find x rounded to the nearest whole number.

Answers

Because x is not defined, it is assumed to be the height of the balloon.

Note that
75° 20' = 75.333°
49° 30' = 49.5°

From the figure shown below, obtain by definition,
a = x cot 49.5° = 0.8541x
b = x cot 75.333° = 0.2617x

Because a + b = 400 ft, therefore
0.8541x + 0.2617x = 400
1.1158x = 400

The width of a rectangle is one half it's length. The perimeter of the rectangle is 54 cm. What are the width and length of the rectangle?

Answers

width= 1/2x length=x
to find the perimeter, it's the width+width+length+length so:
1/2x+1/2x+x+x=54
3x=54
x=18
the length is 18 cm and the width is 9 cm

Let length of the rectangle = x.
Let width of the rectangle = x/2 (or 1/2 of x)

Remember that Area = 2L + 2W, so . . .

2x + 2(x/2) = 54

2x + (2/2)x = 54

2x + x = 54

3x = 54 --> x = 54/3 --> x = 18

So the length of the rectangle is 18 cm and the width is 18/2 = 9 cm.

Multiplying both sides by n, we get 360=((n-2)*180)*1/3. After that, we divide both sides by 180 and multiply both sides by 3 to get 6=n-2. Therefore, n=8 and it is an octagon

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Suppose the base of the pyramid has length = L units and width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (L × B × H) / 3

V = (Base area x H) / 3

The volume of a pyramid varies jointly with the base area of the pyramid and its height.

The volume of one pyramid is 24 cubic inches when its base area is 24 square inches and its height is 3 inches.

Then the volume of a pyramid with a base area of 15 square inches and a height of 7 inches will be

V = (15 x 7) / 3

V = 35 cubic inches

Hence, the volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.
